ISAAC WISVVELL, OF SPRINGFIELD, VERMONT.

COMBINED WINDOW NET AND SASH.

Specification of Letters Patent No. 30,370, dated October 9, 1860.

To all whom it may concern:

Be it known that I, ISAAC WIswELL, of Springfield, in the county of vWindsor and State of Vermont, have invented a new and useful Combination of Window Net and Sash; and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, making part of this specification, in which* Figure l represents a window frame and sash with the net applied to the same. Fig. 2 is a vertical transverse section taken in the plane indicated by the red lines in Fig. l.

Similar letters of reference indicate corresponding parts in both figures.

To enable those skilled in the art to fully understand my invention I will proceed to describeits construction and operation.

The invention is intended to be applied to windows of any and every description where they have sashes that raise and lower, and in windows of the most common description. The plan which I will now describe will suflice to illustrate the application of my invention to such windows.

In t-he drawings, A, represents a window frame, and B, B, the sash thereof-B, the upper sash and B the lower one.

D, D are plain rollers that are hung in suitable brackets, which rollers may be placed respectively above and below the window frame head, and sill, so that they will be out of sight and out of the way, or they may be placed as represented in the drawings, and hung in such a manner that they may be removed during the day and replaced at night or they may be arranged in any suit-able and convenient place as may be desired. Around these rollers are wound the two pieces of netting which should be as wide'as the inside of the window-frame. 'Ihe end of each piece of netting is securely attached to the top of one and bottom of the other window sash, as shown in Fig. 2. The opposite ends are attached to the rollers. Now it will be seen that by raising the lower sash B, the netting from the lower roller will be unwound and if the sash be fully raised the net will cover up the space completely, and so also with the upper sash B. In order that the netting be again wound up on the rollers when either sash is returned, or when the window is closed, the top roller is furnished with a weight and cord that may be hung out of sight or made suiliciently neat and handsome to serve as an ornament. The bottom roller is acted upon by a spring inclosed within a box Gr, Fig. l, which will wind the netting up when the lower sash is brought down. The netting on the rollers is represented in Fig. l, in blue lines, and the net-ting when unrolled by drawing down the top sash is represented in red lines Fig. l.

From this description it will be seen that all the advantage of a mosquito net, applied to a window may be obtained without in the least incommoding the use of t-he window, while at the same time the window sash may be operated conveniently, and when the netting is not in immediate use it will be rolled up and protected from injury. r

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

The arrangement of the nettings and rollers D, D, with the sashes B B, in the manner herein shown and described so that when either of the sashes are opened the netting will follow the sash and protect the open Space and when either sash is closed the netting appended thereto will be rolled up, all as set forth.

ISAAC WISWELL.
